FLUSHING-TANK.

Specification of Letters Patent.

Patented N w. 2, 1909.

To all whom it may concern;

Be it known that I, CHARLES Mnn'rs FRANZHEIM, a citizen of the UnitedStates, residing at Wheelin in the county of Ohio and State of Westirginia, have invented a new and useful Flushing-Tank, of whichthefollowing is a specification.

This invention relates to flushin tanks and more particularly to meansfor ushing closet bowls and other articles requiring a cushion toprevent splashing, detonation,

and unnec ssary mechanical noise incident to the flush ing operation.

A further object is to utilize the body of water in the flushing tank toretard violent or hurried deliver of the water to the tank, closet bowl,or ot er device to be flushed.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability and sanitarefiiciency.

Further objects and advantages will ap: pear in the followingdescription, it being understood that various changes in form,proportions and minor details of construction may be resorted to withinthe scope of the appended claims. y

In the accompanying drawings forminga part of this specification:-Figure 1 is a transverse sectional view taken on the line l1 of Fig.2. Fig. 2 is a longitudinal sectional view taken on the line 22 ofFig. 1. Fig. 3 is a similar view taken on the line 3-3 of Fig. 1. Fig. 4is a top plan view of the tank wlth the bowl removed.

Similar numerals of reference indicatecorresponding parts in all of thefigures of the drawm s.

The improved flushing tank forming the subject matter of the presentinvention may be used in connection with water closets or other articlesrequiring flushing in their opv eration, and by way of illustration isshown in connection with a closet of the siphonic type in which 5designates the bowl, and 6 the flushing rimrovided with a series of-flushing jets, ind cated at 7. The bowl 5 and tank 11 may be formed ofporcelain,

iron, wood or other material, or combination of materials and isprovided at the rear end thereof with a casing 8 formed integral withthe body of the bowl and defining a waterreceiving chamber or reservoir,indicated at 9, the' contents of the chamber '9 being discharged intothe bowl 5 through the orifices 7 and 10.

-Dis osed above the casing 8 and preferably ormed integral with the bodyof the bowl 5 is a fiushmg tank 11 and arranged within said tank 11 is asiphon 15, the down leg 16 of which communicates with the interior ofthe chamber 9, while the up leg 17 is provided at its lower end with aflared extension 18 communicating with the interior of the tank.

Secured to one wall of the tank 11 at a a point above the extension 18of the siphon is a shelf or deflector 20 which serves, in

this case, to direct the water entering the tank into the mouth ofthe-extension 18 of the siphon during the flushing operation.

Disposed on one side of the bowl ,5 is a water supply pipe 21 having itslower end provided with a cut ofi' valve 22' and its upper end providedwith an automatic flushing valve 23, of any approved construction, therebeing ashort pi c section 24 extending from the ushing va ve 23 to thelower or other portion of thetank 11 for forcin a stream of-water underpressure through th water in the tank 11 into the mouth 18 o t e siphon15.

The water in the tank 11 acts as a cushion to prevent splashing,detonation, mechanical hammering, and other unnecessary noise incidentto the flushing operation, and also serving to retard violent or hurrieddelivery of water to the tank or other article to be flushed.

A drain opening or passa e 25 is formed e bod of,

So I

accumulated in the chamber or, reservoir 9 may seep through the drain 0ening1 or passage 25 1nto the bowl for refil ing t e latter after theflushing operation. A drain opening 26' may also be formed in the downleg 16 of the tank siphon for a similar purpose, it being here statedthat either drain opening may be employed but if desired, both may beused to effect the refilling of the bowl.

The cover 14 of the flushing tank is preferably formed with a series ofperforations 22, 1trhereby to admit air to the interior of the tan Inorder to effect the flushing of the bowl, the lever 28 of the flushingvalve 23 is depressed, which causes a stream of water at city pressureto enter the tank 11. The mouth of the supply pipe 24 being disposed atone end of the tank, the water entering the tank through the pipe 24will be directed into the mouth 18 of the siphon, and thence into thechamber or reservoir 9 and through the apertures 10 into the flushingrim 6, a portion of the water from the tank 11 being delivered to thejet 30 through the opening or groove 25, as indicated by dotted lines inFig. 2 of the drawings, for siphoning the water in the bowl. The valve23 is of the usual slow acting type so as to permit the tank 11 to berefilled before the valve 23 acts to automatically .cut off the flow ofwater into said tank.

While I have shown and described the flushing tank supported by andintegral with the bowl, it is obvious that said tank may be spaced fromthe bowl or supported over-head and connected with the bowl or otherarticle to be flushed through themedium of a suitable pipe, withoutdeparting from the spirit of the invention.

Having thus described the invention what is claimed is 1. Thecombination with a bowl or' other article to be flushed, of a flushingtank having a curved wall, a siphon disposed within the tank and havingit mouth opposite the curved wall of the tank, and means for dischargingwater under pressure within the tank against said curved wall, thereb tooperate the siphon to effect the flus ing operation.

2. The combination with a bowl or other article to be flushed, of aflushing tank having a curved wall, a siphon disposed within the tankand having its down leg opening at the curved wall of the tank, andmeans for discharging water under pressure against the curved wall ofsaid tank, thereby to operate the siphon, the water in the tank servingas a cushion to prevent splashing, detonation or violent action of thewater during the flushing o eration.

3. The combination with a bowl or other article to be flushed, of aflushing tank having a curved wall, a siphon disposed within the tankand having one leg thereof extended in the direction of and spaced fromthe curved wall of the tank, and means for forcing a stream of waterunder pressure against saidcurved wall and into the up leg of thesiphon, thereby operating the siphon.

4. The combination with a bowl or other article to be flushed, of aflushing tank, a siphon disposed within the tank and having one legthereof extended in the direction of the water supply, a shelf extendingfrom one wall of the tank, and means for discharging a stream of waterunder pressure into the up leg of the siphon to effect the operation ofthe siphon.

5. The combination with a bowl or other article to be flushed, of aflushing tank, a siphon disposed within the tank and having one legthereof provided with a drain opening, and means for forcing a stream ofwater under pressure through the water in said tank to effect theflushing operation.

6. The combination with a bowl or other article to be flushed, of aflushing tank having vertically disposed side walls, a shelf disposedwithin the tank, a siphon disposed within the tank and having a long legthereof in communication with the bowl and its opposite leg providedwith'a lateral extension, the mouth of which is arranged below theshelf, and means for discharging a stream of Water under pressurethrough the water in the tank and into the short leg of the siphon toeffect the flushing operation.

7. The combination with a bowl or other article to be flushed, of aflushing tank, a siphon disposed Within the tank and having one legthereof communicating with the bowl and its opposite leg provided with alateral extension, a shelf secured to the tank in advance of the siphon,and means for discharging a stream of water through the liquid in thetank, thereby to operate the siphon to effect the flushing operation,there being a drain opening formed in one leg of the siphon to permitrefilling of the bowl after the flushing operation.

8. The combination with a bowl or other article to be flushed having asiphon and provided with a reservoir, there being a passage formed inone wall of the bowl siphon and forming a source of communicationbetween the reservoir and interior of the bowl, of a flushing tankformed integral with the bowl and reservoir, and a siphon arrangedwithin the tank and having one leg thereof extending within thereservoir and its opposite leg provided with a lateral extensionprojecting in the direction of the water supl2 ply, a shelf secured toone Wall of the tank I in advance of the extension, a supply pipecommunicating with the lower portion of the tank for directing a streamof Water under pressure through the liquid in said tank and into theshort leg of the tank siphon to effect the operation of said siphon,
